Abstract: New 5G technologies bring large bandwidth, ultra-low latency, and high-precision synchronization opportunities for transmission bearer network. At the same time, its virtualization, flexibility, and hierarchical features bring new security challenges. This article describes security risks faced by the transmission bearer network between 5G RAN, 5G Core, MEC, and the Internet. It also analyzes typical security requirements and security protection solutions for the access of 5G RAN, 5G Core, MEC, Internet, and NMS management plane to the 5G transport network. By summarizing new security risks, new requirements, and new protection technologies faced by transmission networks in new 5G scenarios, we hope to provide reference for security requirements and protection technologies during the promotion and construction of 5G telecom networks.
Key words: 5G, transmission, slicing, security, isolation
